Are you ready to explore your next career move with us? ## Description Onshape's Site Reliability Engineering team is looking for a Principal Software Engineer to play a critical role in ensuring the longterm reliability, scalability, and operational excellence of our platform. As a Principal Software Engineer, you will operate with a high degree of autonomy and influence. You will lead complex, crossorganization reliability initiatives, shape reliability strategy, and serve as a technical authority and trusted advisor across engineering. Your work will directly shape the experience of our customers by ensuring the platform is fast, resilient, and dependable. As a Principal Software Engineer, you will help protect customer trust by driving reliability across the entire system lifecycle. This role is ideal for engineers who enjoy solving ambiguous, highimpact problems at scale, influencing system design across teams, and raising the reliability bar for an entire organization. What You'll DoOwn Reliability at Scale * Lead design, implementation, and evolution of reliability, availability, and resiliency strategies for largescale distributed systems written primarily in Java * Apply deep experience operating complex, distributed systems to guide architectural decisions, reliability strategies, and longterm system evolution * Identify systemic risks in application architecture, data flows, and infrastructure, and drive architectural improvements that measurably improve availability, performance, and scalability * Set and evolve reliability standards, best practices, and operational principles across R&D Drive Operational Excellence * Lead efforts to prevent, detect, and mitigate incidents through technical improvements and operational maturity * Serve as a senior coordination point during major incidents, helping manage response and guide longterm remediation * Champion blameless post-incident reviews and ensure learnings translate into durable system improvements Reduce Toil Through Engineering * Apply advanced software engineering practices to eliminate manual work, reduce operational load, and improve system observability * Design and build internal platforms, automation, and tooling that support Javabased services and their operational needs * Raise the bar on monitoring, alerting, and SLO/SLI adoption across systems Lead Through Influence and Collaboration * Partner deeply with product engineers, architects, and engineering leadership to ensure reliability and operability are firstclass concerns in system design * Review and influence designs for complex systems involving technologies such as datastores, messaging systems, and coordination services * Serve as a technical mentor and coach for SREs and other engineers, raising overall engineering and operational maturity Shape Strategy and Direction * Contribute to longerterm reliability and infrastructure strategy aligned with business growth * Stay current with industry trends in SRE, distributed systems, and the Java ecosystem, turning insights into practical improvements * Help define what "great reliability" looks like for the organization and how we measure it, The Principal Software Engineer role is critical to ensuring our platform continues to meet the reliability expectations of our customers as we grow. Your work will have a broad and lasting impact-not only on individual systems, but on how reliability and operational excellence are approached across engineering. ## Related Videos - [Leading with Reliability: Applying SRE Principles to Build Stronger Engineering Organizations](https://www.wearedevelopers.com/videos/100185-leading-with-reliability-applying-sre-principles-to-build-stronger-engineering-organizations) - [What Makes Open Source Work: Licensing and Beyond](https://www.wearedevelopers.com/videos/1416-what-makes-open-source-work-licensing-and-beyond) - [Beyond Kafka & RabbitMQ: Why NATS is the Future of Microservices Messaging](https://www.wearedevelopers.com/videos/1646-beyond-kafka-rabbitmq-why-nats-is-the-future-of-microservices-messaging) - [40 Minutes to Build a Serverless COVID-19 REST and GraphQL APIs](https://www.wearedevelopers.com/videos/208-40-minutes-to-build-a-serverless-covid-19-rest-and-graphql-apis) - [SRE Methods In an Agency Environment](https://www.wearedevelopers.com/videos/348-sre-methods-in-an-agency-environment) - [Going Quantum: The future of the internet ...](https://www.wearedevelopers.com/videos/672-going-quantum-the-future-of-the-internet) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers)
